Ardistomis
Ardistomis is a genus of pedunculate ground beetles (Carabidae: Scaritinae) comprising more than 40 described species distributed across North, Central, and South America. Larval morphology supports classification of ardistomines (Ardistomis, Semiardistomis, and Aspidoglossa) as a subtribe (Ardistomina) within the tribe Clivinini. The genus includes species with documented range extensions, such as A. quixotei, which likely colonized Cuba from Mexico during the Quaternary Period.
